A ball bounces because it changes shape on impact and the momentum from changing the shape back to normal makes it go up again. Then why rock solid stuff also bounce when dropped? Ive seen pebbles bounce when dropped. My phone bounces like 1 or 2 times when i drop it. Why?

Same reason. Either they (and/or the ground beneath them) flex and rebound in the exact same way. It just happens a lot quicker and it’s so subtle that you can’t see it.
Look up slow motion footage of a golf ball being teed off, for example. I would normally consider a golf ball to be a rigid object, but in the instant of impact, it will deform just like a rubber bouncy ball does.
